 Well, good afternoon. We are now going to start the last session of this first edition of the WPC Health Conference. As I told you at the beginning, as I said the opening of this conference, the subject of mental health and addictions is usually not brought at the centre stage when people talk about health care and global health. We have decided to bring this subject for this first edition because we thought that this somewhat neglected subject is actually of the utmost important globally. The mental health of the population, the global population is a key issue and has to be recognised as such. But also there are a number of global governance issues of interdependence issues. There are some obvious geopolitical ramifications such as the illicit trade, drugs, criminality and so forth and so on. This is a subject that we usually discuss at the World Policy Conference. But in fact, when we decided to introduce this subject, we had not thought that the mental health situation could be important in the context of the COVID-19 pandemic. And now everybody becomes aware that a population that is forced into lockdown and other restrictions suffers mentally. So this subject is in fact even more important than we thought initially. And I think that this is even more clear after what we heard this morning because at least twice, for instance this morning in each of the first two sessions, the issue of fake news, trust and so forth and so on was brought into the discussion. And as I think we will see in a minute with Professor Burioni, this issue of fake news, trust is also the core of the mental health and addiction problem. So we are going to start this session with three highly distinguished speakers. And we will start with Mikael van der Berg who is a health economist and policy economist at the OECD to give us the broad picture from the viewpoint of an economist. As I tried to say this morning, the economic aspect is really key when talking about health. So we will start with you Mikael and then we will move to Professor Burioni and we will end with Dr. La Blanchie. So the floor is yours Mikael.
